@ Html.Action post状态模型不会影响partialview

Question

BooksController中的

    [ChildActionOnly]
    public ActionResult CommentForm(int bookid)
    {
        var model = new CommentSurrogate();
        model.BookID = bookid;
        model.Date = DateTime.Now;
        return PartialView("_CommentForm", model);
    }


    [HttpPost]
    [ChildActionOnly]
    public ActionResult CommentForm(CommentSurrogate model)
    {
        if (ModelState.IsValid)
        {
            if (Session["commentSec"] as string == model.SecurityCode)
            {
                model.Date = DateTime.Now;
                CommentRepository repo = new CommentRepository();
                repo.Save(model);
                ViewBag.CommentMessage = "Yorumunuz başarıyla kaydedilmiştir. Editörlerimiz tarafından incelenip onaylandıktan sonra yayınlanacaktır.";
                return PartialView("_CommentForm", new CommentSurrogate {Date = DateTime.Now, BookID= model.BookID });
            }
            else
                ModelState.AddModelError("SecurityCode","Güvenlik kodunu yanlış girdiniz.");
        }
        return PartialView("_CommentForm", model);
    }

BookDetailView中的

@Html.Action("CommentForm", "Books", new { bookid = Model.ID })

当我用评论表写评论和发帖时。使用[HttpPost]属性调用CommentForm操作。而且我正在保存模型，此时没问题。

return PartialView("_CommentForm", new CommentSurrogate {Date = DateTime.Now, BookID= model.BookID });

但_CommentForm似乎没有重新获得上面代码传递的新的CommentSurrogate模型。发布后的评论表格仍然包含当前发布数据的数据。

_CommentForm.cshtml

@model Yayinevi.Data.Surrogates.CommentSurrogate
@using (Html.BeginForm()){
@Html.AntiForgeryToken()
<div id="respond" class="clearfix">

    <div class="title-block" style="margin: 0 0 30px 0;">
        <h3>Kitap Hakkında Yorum Yazın</h3>
    </div>
    @if (@ViewBag.CommentMessage != null)
    {
        <div class="msg success"><p>@ViewBag.CommentMessage</p></div>
    }
    @Html.HiddenFor(model => model.BookID)
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })
    <div class="field-row">
        @Html.LabelFor(model => model.Name)
        @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "text_input" } })
        @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger", style = "display:block;margin-top:-20px;margin-bottom:15px;" })
    </div>
    <div class="field-row">

        @Html.ValidationMessageFor(model => model.Comment, "", new { @class = "text-danger", style = "display:block;margin-top:-20px;margin-bottom:15px;" })
    </div>
    <div class="field-row">

    </div>
